Funny Silkie Noises...does anyone else's roo's do this?

I have 2 Silkie roo's. They are thoroughly entertaining! I've had roosters of different breeds before, so I'm familiar with the "tuck tuck tuck" sound they make when they "found food" for the girls and of course familiar with their crow...VERY familiar with their crow . Anyway, these two boys have another sound I've never heard anyone else make...it's almost like a call to each other because as one starts, the other follows with the same yell immediately as well. It sounds almost like a crow "RAAAH". The other is a low throaty "growl" which I have occasionaly heard the girls put out as more of a warning.

Does anyone else have very verbal silkies or other roos with a large vocabulary? It's very interesting...wasn't sure if was a "silkie" thing or what.

Don't worry, I talk to mine while they are sitting on my lap and they sit outside the front window of my house "calling" to each other (like echoing each other) and are constantly making the strangest little sounds that I never heard come out of a rooster. It's way cute and funny. Guess it's a "silkie" thing

by "trill", do you mean when they just go "rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr"? They do that a lot. I wish I had some hens too, but when I got these 2 that I have, we were hoping either both would be hens or maybe one of each...but since I seem to be a rooster magnet...yep..2 roos.
